How to Plant Coastal Grass

Water the area to be planted to 1/2 inch deep. For large areas, divide the area into quarters and move the sprinkler to each quarter every half hour. Repeat this process twice each day for four days. Using an impact sprinkler is ideal for this task because it will use less water yet still do an effective job.

Spread a 2-inch layer of compost over the area to be planted. The compost must be rich in nitrogen to ensure proper growth. If building your own compost, incorporate a substantial amount of coffee grounds, green waste and wet matter.

Till the area with the rotary tiller, working the soil to a depth of 6 inches. Make several passes over the area to ensure good tilth, or friability. A riding lawnmower with a disc harrow attachment also works well for this task.

Break down any remaining clumps in the soil with a cultivating fork or a garden fork. Work the compost into the soil in any areas where it remains unincorporated.

Dig 3-inch deep holes at intervals of 10 inches across the planting area. Plant the coastal grass plug by placing the rooted end into the hole and pinching the soil in around it. Gently firm the soil around the plug.

Water the newly planted coastal grass to 1 inch of depth. Maintain constant moisture in the area for the first 30 days after planting. The soil must be moist but not waterlogged.

Mow the grass after 30 days and every two weeks from then on. Set the mower to approximately 3 inches high when mowing coastal grass.
